耦合轴子-约瑟夫森结系统的非线性动力学
Nonlinear Dynamics of Coupled Axion-Josephson Junction Systems
摘要：
我们研究了通过任意大小的电容耦合耦合到约瑟夫森结（探测器）的轴子场（信号）的经典动力学。根据耦合常数的大小和初始条件，我们发现这个非线性问题的丰富的相空间结构。我们提出了一般的解析解的运动方程的角度变量的小振幅的限制，并讨论了无耗散和耗散的情况下的系统。磁场的影响进行了研究，以及，导致拓扑相变的相空间结构。
英文摘要：
We study the classical dynamics of an axion field (the signal) that is coupling into a Josephson junction (the detector) by means of a capacitive coupling of arbitrary size. Depending on the size of the coupling constant and the initial conditions, we find a rich phase space structure of this nonlinear problem. We present general analytic solutions of the equations of motion in the limit of small amplitudes of the angle variables, and discuss both the case of no dissipation and the case of dissipation in the system. The effect of a magnetic field is investigated as well, leading to topological phase transitions in the phase space structure.
